求个外部变量得function值的问题

function popSignFlow(isLogin,LId) {
  popSign(isLogin);
  LnzID=LId;
  document.body.style.overflow = "hidden";
  return (LnzID);
//LnzID这值已经得到了
}
var sign_in_flow = '<form action="../222.asp?Id=+popSignFlow("aaa","bbb")+"  method="post">';

var LnzID;
popSignFlow(isLogin,LId)//使用前调用下函数
var sign_in_flow = '<form action="../222.asp?Id='+LnzID+'" method="post">';

首先很感谢大家的热情帮助，但是以上的代码我都测试了，都是有问题的
var sign_in_flow = '<form action="../222.asp?Id='+LnzID+'" method="post">';
这是调用不到他的变量值
还有说明下
sign_in_flow
这个变量不在任何方法内只在<script></script>里

估计是执行顺序的问题．
var sign_in_flow = '<form action="../222.asp?Id='+LnzID+'" method="post">';这个不在<script>里，那怎么执行啊，不是直接打在页面上了？

以上的都是源码，为了这个问题搞了一上午，实在搞不懂哪里出问题了，所以没办法才麻烦下大家

执行顺序问题，上面那个是写在函数里的，函数要用户点<a>才触发，下面那个上来就执行了，这个时候用户还没点怎么能得到值，改成下面这样
var sign_in_flow = "<form name="newForm" action=\"../222.asp?Id="+LnzID+"\" method=\"post\">"
LnzID=LId;这句也要改
newForm.action="../222.asp?Id="+LId
还有下面的那个sign_in_flow参数没调用啊
